Hi all looking for advice in solving a problem I have?.. I have installed a 3 gang WiFi smart switch. 2 of the switchs are working as they should. Wiring I have.. Black/red/earth x2..red/earth x1. How its working.. Earth's to back plate together.. Single red to L. 2 blacks to N. Other reds to L 1 & L 2..these are working fine... 3..empty...how do I get L 3 to work?.. Is there a loop way?.. Any advice would be great thanks..

Don’t suppose you took a photograph before you took the old switch off?

Are you sure the black cables are neutrals? How were they connected at the old switch?

 

[telectrix]

the 3rd switch will not do anything because there's no cable coming out of L1.

 

[Sean]

No I'm not sure they are neutrals but 2 switchs work.. I did try moving black wires. One left in N. Other to L1.. This left no power one way. And made no difference the other..

Have you got two way switching where one light is controlled by two switches.

 

[Sean]

Yes but other switch doesn't do anything now..
